The Mechanical Analysis and Test (MA&T) Department is responsible for ensuring structural and thermal design robustness across the Raytheon portfolio of products.  From preliminary concepts to fielded weapon system support, MA&T delivers innovative structural and thermal engineering solutions utilizing methods ranging from classical fundamental & empirically based techniques to state-of-the-art finite element methods leveraging industry leading commercial tools; all complimented and validated by tests executed in a manner to ensure cost effective yet technically balanced solutions.

The Senior Mechanical Engineer – Structural Analysis position is located in Marlborough, MA, and the role is onsite.

As the Senior Structural Analysis Engineer, you will be responsible for detailed structural analysis to support all phases of programs including development and production. The analysis will cover a wide range of difficult problems, requiring solutions that are imaginative, thorough, practicable, and consistent with organization objectives. The analysis tasks will span the spectrum from classical hand calculations to detailed analyses requiring the use of finite element analysis software. You will be expected to define the scope and level of analysis required to meet the objectives and will be held accountable for completing the work within the agreed upon cost and schedule. You will be expected to present your work for peer reviews and to be a peer reviewer for other engineers’ work. The customers of this position will include internal personnel and programs as well as external Government(s) personnel and programs.

What You Will Do: • Perform detailed structural analyses to support all phases of programs • Generate test plans required to validate analyses and verify hardware compliance to customer requirements • Analyze test data to validate and correlate models, and/or generate mechanical loads and environments • Work with limited oversight on complex problems to provide the answers needed under program cost and schedule constraints • Coordinate and lead technical peer reviews ensuring the technical accuracy of work products as well as acting as a reviewer for others work products • Present results to internal stakeholders and external customers • Generate detailed, archival technical reports • Travel to test sites to support test or design discussion (depending on work assignment) • Act as a technical leader (help define and develop MA&T department technical processes and tools) and lead teams to meet program milestones

Qualifications You Must Have: • Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 5 years of prior relevant or An Advanced Degree in a related field and minimum 3 years’ experience • Experience in structural analysis (i.e. PATRAN, NASTRAN, ANSYS, ABAQUS or equivalent software)

• Working knowledge of mechanical principles to solve classical structural engineering problems both inside and outside of software tools • Ability to work in a collaborative, team-based environment and independently • Ability to obtain a U.S. government issued security clearance. U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance, Clearance must be active and transferable prior to start date

Qualifications We Prefer: • Working knowledge of mechanical principles to solve classical structural engineering problems both inside and outside of software tools • Ability to work in a collaborative, team-based environment and independently • 8+ years of professional experience in the structural analysis of complex systems that require collaboration of multiple engineering disciplines (such as a weapon system) • Experience in structural testing: planning, organization, execution, data reduction and correlation • Experience with shock and vibration analysis • Experience with solid modeling CAD tool such as CREO or equivalent • Experience with Matlab • Experience leading teams and strong interpersonal skills working in a team environment • Experience presenting to external customers • Ability to travel to government and other facilities in support of program activities • Advanced degree in aforementioned disciplines. ABET is the preferred, although not required, accreditation standard.
